    libide/gui: add secondary workspace action for workbench
    
    This adds context.workbench.workspace.new and some plumbing for it to be
    called through other measures too. I'd like to remove the layer violation
    here at some point, but for now it's good-enough given the libide-editor
    is also internal library/plugin.
